If your tank is new (under 3 months) it is just a diatom bloom. Every new tank gets it, it is harmless and will go away on its own.

this is not a new tank, it is 3 yrs. old. is there and fish i could get that will help eat some of the alge? i have a spotted grouper about 4in, and huma trigger, black trigger, and a yellow tang

Do you have any snails? What does your cleanup crew consist of?

Is it short brown strands of algae that branches out? Also, do you have a refugium with mudd in it?
